This study is a multicenter, observational, prospective study to evaluate the asthma biologic use features and clinical outcomes in China. Patients will undergo clinical assessments and receive standard medical care as determined by the treating physician. Approximately 200 patients with a physician diagnosis of asthma and prescribed with asthma biologics at visit 1 will be enrolled in this study, distributed among 50 sites across different regions in China. During the study period, patients will be identified consecutively and, if they meet eligibility criteria and provide informed consent will be entered into this observational study. Patients should have an asthma diagnosis and be prescribed at least once with biologics for asthma treatment at enrollment (Visit 1, Week 0). After the enrollment, subjects will be followed up at Visit 2(Week 24) and Visit 3 (Week 52). V1, V2 and V3 will be followed up by on-site visit. At Visit 1, data within last 12 months will be retrospectively collected as baseline. Patients existing medical record (MR) data will be collected in week 24 and week 52. PROs (Asthma control test [ACT], Asthma Quality of Life Questionnaire (+12) [AQLQ(S)+12]) should be performed at Visit 1, Visit 2 and Visit 3. No additional mandated interventions on top of routinely performed physician visits, examinations or treatments will be required. Patients will not receive any experimental disease management intervention or experimental treatment as a result of their participation in the study.
